Of each such pair, one 15 easily tilted either upwardly and rearwardly or link I2 is connected at its forward end to an upwardly and forwardly to provide convenient upper forward portion of the end wall and at its access to the interior of the receptacle for purrear end with the rear portion of the roof memposes of cleaning or inspecting the same or reber R as by means of a connection to the triangu- 2 plenishing the supply of feed therewithin. lar member II.

It will be seen i Re e r o the drawing, I have Shown an that during upward and rearward tilting of the bodiment of my inv associated with a roof member R the bar I2 connected to the fortrough T which is preferably suppo f ward portion of the roof member R swings up- 45 zontal supportmg stnps 5 and whlch wardly and rearwardly and that the bar l2 con- {nounted by a roof member i .fgi g nected to the rear portion of the roof member includes a front wall 6 and a rear .wal ispose R swings downwardly. The movement of the longitudinally thereof and end walls 8 and 9 and b ars 12 during upward and forward tilting of the an intermediate wall l0. disposed transversely of roof member R is the ht to be apparent from the trough. The transverse walls 8, 9 and I0 are of uch as to project a ubstantial Flg. 3 and above explanatimfl. 'I'h-e distance above the upper limits of the longitudimovement of the o member i Preferably n31 walls 6 and I and at, their upper edges support limited by use Of suitable stop means and it will 65 the roof member R. The roof member R is prefbe seen from Fig. 3 that the rolled upper edge of the front and rear walls 6 and 1 function as stop means for this P rp se.

I provide means for holding the roof member R in the normal position thereof shown in Fig. 1. A form of such holding or retaining means is shown in Figs. 2 and 4. I provide the centrally located one of the triangular members II with a horizontallydisposed flange Ila along its lower edge and provide suitable latch means on 10 the centrally located transverse wall II for engagement with the flange Ila. My latch device comprises a flat bar Ii bent into the general form ofan ssoastoprovideahook liainitsupper portion for engagement with the upper side of the flange Na and an operating bar lib in its lower portion. The medial portion of the bar I i is rockably connected with the transverse wall III.

A rivet loosely connects the bar lib to the wall it. The desired looseness is obtained by provid- 2 ing aligned aperturesin the bar and the wall ll of larger diameter than the shank of the rivet I4 and installingthe rivet with the respective heads thereof 'suillciently far apart to avoid clamping of the riveted members therebetween. Above the rivet M a cotter key I! is extended through aligned apertures in the bar li and wall Ii and the free ends of the cotter key are bent to prevent withdrawal of the cotter key. A helical compression spring I6 is disposed between the head of the cotter key and the outer side of the bar Ii. Release of the hook lia from the flange Ila is eil'ected by pressing the handle lib downwardly to rock the bar li against the pressure of the' spring l8, whereafter the roof member R may be tilted forwardly or rearwardly, as desired.

The hook lid is so shaped that the flange will i cam the hook lia out of its way as the roof member R is returned to its normal position whereafter the spring It will return the hook lid into 40 flange-engaging position.

To provide for cleaning of beaks by the poultry, a wire i1 is extended through suitable apertured portions of the transverse walls 8, ii and i, as shown.

It is apparent that I have invented a novel, con-' venient, compact and inexpensive form of poultry feeder including a roof member readily tiltable either forwardly or rearwardly and normally held in position by self-engaging and easily releasable latch means.

It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the various parts without departing from the scope of my invention.

What is claimed is:

1. Poultry feeding apparatus comprising an o'pen topped receptacle, a roof member normally resting on portions of said receptacle, a relatively rigid element swingably connected at its respective ends to a forward portion of said roof memher and a rearward portion of said receptacle, and a second relatively rigid element swingably connected at its respective ends to a rearward portion 85 of said roof member and a forward portion of said receptacle whereby said elements will guide said roof member in forward and rearward tilting movements thereof relative to said receptacle.

2. Poultry feeding apparatus comprising an open topped receptacle having front, rear and end walls, said end walls projecting above the upper limits of said front andrear walls, a roof member normally resting on the upper edges of said end walls, a relatively rigid element swingably connected at its respective ends to the front portion of said roof member and an upper rear portion of said receptacle, and a second relatively rigid element swingably connected at its respective ends to the rear portions of said roof member and an walls, a roof member normally resting on the;

upper edges of said transverse walls, a relatively rigid element swingably connected at its respective ends to the front portion of said roof member and an upper rear portion of one of said transverse walls, and another relatively r id element connected at its respective ends to the rear portionofsaidroof memberandanupperforward portion of one of-said transverse walls whereby said elements will guide said roof member in forward and rearwardtilting movements thereof.

4. Poultry feeding pparatus comprising a relatively elongated open topped receptacle having front, rear and end walls, said end walls projecting above the upper limits of said front and rear walls, a roof member normally resting on the upper edges of said end walls, a relatively rigid element swingably connecwd at its respective ends to the front portion of said roof member and an upper rear portion of one of said end walls. and another relatively rigid element swingably connected at its respective ends to the rear portion of said roof-member and an upper forward portion of one of said end walls whereby said elements will guide said roof member in both for- I ward and rearward tilting thereof.

5. Poultry feeding apparatus comprising an open topped receptacle having front and rear longitudinal walls and transverse walls. said transverse walls projecting above said longitudinal walls, a roof member normally resting on the upper edges of saidtransverse wall, a pairof relatively rigid elements disposed adjacent respective ends of said receptacle and each swingably connected at its respective ends to a forward portion ofsaidroofmemberandanupperrearportion of said receptacle, and a second pair of relatively rigid elements disposed adjacent respective ends of said receptacle and each swingably connected at its respective ends to a rearward portion of said roof member and an upper forward'portlon of said receptacle whereby said elements will guide said roof member in both forward and rearward tilting movements thereof.

6. Poultry feeding apparatus comprising a relatively elongatedopen-topped receptacle having front, rear. end and bottom walls. said end walls projecting above the upper limits of said front and rear walls, a roof member normally resting in its respective end portions on 'the upper edges oftherespectiveendwalls,andmeanshingedly connecting said roof to saidreceptacle for fora roof member and the remaining end wall in a manner corresponding to that of said first two bars.

7. Poultry feeding apparatus having, in combination, a trough structure, a roof for said structure normally resting on portions thereof, means permitting, guiding and limiting tilting movements of said roof member in an upward and rearward direction and in an upward and forward direction, and releasable retaining means for connecting a central portion of said roof member to a central portion of said trough structure when 5 said roof member is in normal position.
